OPERATING DEVICE FOR HEATERS.

Application filed February 18, 1920. Serial No. 359,672.

To all whom it may concern: 1

Be it known that I, JAMES O. GAZE- NovE, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Operating Devices for Beaters, of which the following is a specification.

My invention relates to an improved form of egg beater of the type operable by hand; and an object of my improvement is to provide a beater which will automatically reverse the motion of its beating-blades while the operating handle revolves always in one direction, it having been determined that such reversing motion increases the speed and effectiveness of the beating operation; another object is to accomplish this periodic reversal of motion by using but one driving gear; and a further object is to provide a frame to house suitable bearings for the beater blades, driving wheel, and handle, which can be punched out economically from a single piece of material.

I attain these. objects by the invention illustrated in the accompanying drawing, in which- Figure 1 is a side elevation of my complete egg beater; and Fig. 2 is another slde elevation of the same, as seen from a plane at right angles to that of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

The frame 1 consists of astrip" of flat steel of the shape shown and of suitable thickness, from which a rectangular lip 1*, Fig.1, is first punched, leaving thereby an opening 18, Fig. 2. The stripis then bent to the form shown in the drawings, thereby providing at its upper end means for attaching a handle 9, which means consists, for instance, of riveting another flat piece 2 in position shown, and connecting part 2 and upper end or bent section ofl with a.

small wire rod surrounded by a coiled spring handle. Or any other suitable form. of handle, of course, be substituted. Also, near its middle section, frame-piece 1 is widened out and twisted at right angles to the plane of its upper end portion, so as to provide a housing for the driving-gear bearing; and

at its lower end section it is bent substantially as shown, to include tWo lips, one of them being punched-out lip 1 these lips projecting at right angles across the longi.

tudinal axis of the'beater, and containing two pairs of holes in alinement to serveas in ear '3 that the teeth 5 engage the teeth b L? of p1n1on 10 on one SlClB'Of said p1n1on during substantially one-half a revolution of the operating handle 8 which actuates the driving gear 3, through arm 7 riveted at 6 to hub 3 and during the other half revolution teeth 4 engage the pinion-teeth at a' point on the pinion diametrically opposite the first named point of mesh. By this means pinion 10 with its beater blades 13 and 15 positioned at right angles to each other, is caused to revolve periodically in opposite directions, although operatinghandle 8 is revolving in but one direction.

Rigidly attached to the shaft which mounts pinion gear 10, and between the two bearin supports of frame 1, as shown, is a small spur gear 11, its teeth meshing into the teeth of a similar-sized spur gear 12, which gear is keyed to the shaft mounting beater blades 14 and 16, which blades are also positioned in planes at right angles to one another, as are blades 13 and 15. In this manner blades 13-15 are caused to revolve always in'an opposite direction from blades 1416, thetwo sets of bladesalso revolving within each other without interference.

It will thus be seen that my invention discloses a practical means of periodically changing the direction of rotation of the beater blades automatically, and by means of but one driving gear whose teeth are arranged to alternately engage opposite edges of the driving pinion, and, further, that the frame holding the various parts of the completed beater shows a novel construction adapted to economical manufacture.

The operation of my improved egg beater is exactly similar to that of other well-known heaters now universally used, the result only combination of a supporting frame, a hub V pivoted in the frame and provided with a andle, a circular disk centrally mounted on the hub, a pair of sector plates provided 1 with bevel'teeth on their peripheries and so positioned on opposite sides of the circular disk that the bevel teeth of each sector plate face toward the disk but on opposite sides of the hub, a bevel-toothv pinion journaled in lateral extensions of the frame and disposedqto vmesh alternately with the bevel teethof each sector plate, the disk, hub, and plates being all integrally attached, and a pair of spurge'ars operatively connected to the bevel pinion and mountedin the lateral upper of said extensions being pressed out from the body of the vertical portion, a driving gear having diametrically-opposed beveltooth sectors and journaled in the vertical portion, a bevel-tooth pinion disposed'to' mesh alternately with the teeth on each'sector, and a pair of spur gears operatively con nected with each other and the pinionand journaled in the horizontal extensions,

3. In a device for operating beaters, a sheet metal supporting frame including, a pair of arms secured to the ends of a coiledwire handle, a member integral with one of said arms but twisted to lie in a plane at right angles thereto and perpendicular .to the axis of the handle,'a pair of lateral ex"- tcnsions formed on the lower end of-said member, one of whichis pressed out from the body of the member, a driving gear hav ing a central hub carrying two integrallyattached bei elfgear sectors and a handle and journaled in the member, a bevel pinion and two spur gears journaled'in the lateral ex-,

tensions and operatively connected to the driving gear.

Signed at New York, in the county of New York and Stateiof New York this 14th day of February, A. D. 1920.
